Abstract

The aim of this study was to evaluate the characteristics of ruptured aneurysms at anterior communicating artery (A com) with an analysis of clinical and morphological data, which could further our understanding of the risks of ruptured A com aneurysms. An analysis of data with 86 ruptured and 44 unruptured A com aneurysms were analyzed using a digital subtraction angiography or 3-dimensional computed tomography angiography between January 2010 and December 2015 in a single center. Fifty-five percent of ruptured A com aneurysms were smaller than 4 mm in size. They had a smooth wall (44%), with a mean size ratio of 4.22 (range: 0.7-14.3) and mean height/width ratio of 1.48 (range: 0.5-2.9); 23 patients of A1 positive difference. Unruptured aneurysms were mostly 2-10 mm in size (94%) and had an irregular wall (43%), with a mean size ratio of 4.1 (range: 0.8-9.1) and mean height/width ratio of 1.2 (range: 0.1-2.6); 6 patients of A1 positive difference. In terms of the morphology of aneurysms, size of A com, maximum aneurysm size, neck width, aneurysm wall morphology, and size ratio were not different with statistical significance. However, dominance of A1 (p = 0.01) and height/width ratio (p = 0.03) were found to be a significant ...Continue Reading
